Hot off the heels of his Republican National Convention keynote address, New Jersey Governor Chris Christie made his second appearance on “Late Night with Jimmy Fallon” Tuesday, where he discussed his keynote address, joked about his son leaving for college and belted out a Springsteen classic without missing a beat.

The 49-year-old kicked off the segment by telling Fallon about the unexpected backstage encounter he had with Mitt Romney as he was getting ready to deliver his prime-time address.

“He stopped and he said to me, ‘You’re going to be good tonight, right?’” Christie recalled. “And I said ‘Yeah, I’m going to be real good.’”

“In case it wasn’t enough pressure with like 20 million people, you know, now we have Mitt Romney hanging for the speech,” Christie joked.

Also up for discussion was Clint Eastwood’s much talked about speech. Christie said he didn’t know what the legendary actor had planned for that evening, but he knew the “Dirty Harry” star had gone “off the rails a little bit” when he made an off-color remark to an empty chair about Romney not being able to “do that to himself.”

The father of four also spoke about his eldest son leaving for college. Although Christie admitted to feeling a bit emotional about his son going away to Princeton, he joked that his son was likely feeling otherwise.

“Literally three-quarters of a mile from the center of campus is the governor’s mansion, and we don’t live there so it’s empty,” Christie said. “How many guys can give this line to a girl in college: ‘Hey, would you like to come back with me to the governor’s mansion?’”

Christie, who saw his 130th Bruce Springsteen concert in Philadelphia a few nights ago, gamely helped Fallon wrap up the segment by belting out the Springsteen hit “Thunder Road,” in tribute to their musical idol. Christie posted a video of the performance on his YouTube channel.
